TL;DR: In this review, different strategies to stabilize multimeric enzymes at different levels are revised and special emphasis is put on the new immobilization strategies specifically designed to involve the maximum amount of enzyme subunits in the immobilization (and thus, in the further multipoint covalent attachment).

TL;DR: The compiled evidence of high pressure enzyme enhancement indicates that pressure is an effective reaction parameter with potential for greater utilization in enzyme catalysis.

TL;DR: In this article, the performance of the columns under several flow rates and leachate strengths was studied in terms of BOD 5 removal efficiencies and electricity generation, when a fixed resistive load was connected.

TL;DR: In this article, a batch process that produces H 2 without inoculum addition was devised based on two facts: (1) the abundant indigenous microflora found within organic solid wastes and (2) batch H 2 production completion times being in the same range with hydraulic retention times at continuous processes.

TL;DR: In this article, an innovative fermentation scheme was designed, co-culturing immobilized Zymomonas mobilis and free cells of Pichia stipitis in a modified fermentor for the glucose and xylose fermentation, respectively.

TL;DR: Nine cellulolytic bacterial strains were isolated from soil sample taken in southern Taiwan through 16S rRNA sequence matching and HPLC analysis confirmed the bacterial hydrolysis of these cellulosic substrates for soluble sugars production.

TL;DR: In this article, the enzymatic saccharification of three different feedstocks, rice straw, bagasse and silvergrass, which had been pretreated with different dilute acid concentrations, was studied to verify how enzymatics were affected by the lignin composition of the raw materials.

TL;DR: In this paper, the results showed that glucose and Mg 2+ are the key ingredients for laccase production with the optimum concentration of 00988g/mL and 73mmol/L respectively.

TL;DR: In this article, the effects of initial medium pH and gas flow rate on Clostridium ljungdahlii and C. autoethanogenum in liquid batch, continuous gas fermentations were investigated.

TL;DR: In this article, an Escherichia coli metabolically engineered to ferment lignocellulosic biomass sugars to succinic acid was tested for growth and fermentation of detoxified softwood dilute sulfuric acid hydrolyzates, and the minimum detoxification requirements were investigated with activated carbon and/or overliming treatments.

TL;DR: The deduced internal amino acid sequence of the Salinivibrio sp.

TL;DR: 12 new water immiscible ionic liquids with adequate distribution coefficients were evaluated with respect to their applicability in biphasic asymmetric reductions of prochiral ketones in comparison to 9 already published ILs.

TL;DR: The purified CMCase hydrolyzed carboxymethylcellulose (CMC), cellobiose, filter paper, and xylan, but not avicel, cellulose, and p -nitrophenyl-β- d -glucospyranoside (PNPG).

TL;DR: Investigating the role of compatible solutes, extracellular polysaccharides (EPS), and nutrients on anaerobic biomass when stressed with salinity showed that methanogens were more protected than propionate utilisers, and a higher production of EPS was obtained from biomass exposed to higher salt concentrations.

TL;DR: In this paper, the authors investigated the bio-leaching kinetics of the fungus in the presence of the fly ash at various pulp densities (1-6%) in a batch system.

TL;DR: Solid-state fermentation of castor bean waste by Penicillium simplicissimum may increase the utility of the waste by promoting enzyme production and eliminating the principal toxic element, ricin.

TL;DR: This study contributes for the structural requirement of a dye to be degradable by P. desmolyticum laccase and is important in order to optimize potential bioremediation systems for industrial textile process water treatment.

TL;DR: The potential of laccase-facilitated grafting of amino acids to high-lignin content pulps to improve their physical properties in paper products is demonstrated and an increase in strength properties of the resulting paper is shown.

TL;DR: In this article, the effects of inorganic selenium (sodium selenite) and Selol containing selenitetriglycerides synthesized from sunflower oil on mycelial growth and SEPS and IPS polysaccharides production were examined in shake flask cultures of Hericium erinaceum.

TL;DR: The degradation of the components of Japanese beech and Japanese cedar wood was measured over time in cultures of the white-rot fungus Ceriporiopsis subvermispora in this article.

TL;DR: A mixed consortium of sulphate-reducing bacteria was used to investigate the enzymatic mechanism for the total bioreduction of platinum (IV) into platinum (0) nanoparticles and it was found that the Pt(IV) ion must be fully reduced before reduction of the Pt (II) ion would begin.

TL;DR: Rhodococcus sp. Moj-3449 as discussed by the authors was found to have subterminal oxidation pathway and showed the ability of rapidly degrading long chain n-alkanes and crude oil at high concentration.

TL;DR: In this article, the composition and dynamics of the microbial community in a propionate-fed upflow anaerobic sludge bed (UASB) reactor with sludge originating from an alcohol distillery wastewater treating UASB reactor was studied.

TL;DR: The results imply that cultivation of S. sclarea hairy roots in sprinkle bioreactor after elicitation with MJ may be valuable to enhance production of the bioactive diterpenoids.

TL;DR: Results indicated that complete cellulase could either peel the fibrillar bundles along the microfibrils (peeling) or cut microFibrils into short length across the length direction (cutting) during the hydrolysis of a fully bleached reed Kraft pulp sample.

TL;DR: In this paper, the authors used two enzymes, i.e., acetylcholinesterase and choline oxidase within separate hybrid mesoporous silica membranes with 12-nm pore diameter (F127M), to detect hydrogen peroxide produced by two sequential enzyme reactions.

TL;DR: In this paper, a neutral metallo-endopeptidase enzyme-assisted aqueous extraction process, optimized for effectiveness in reducing oil content of the solid residue, yields a small fraction of the oil as free oil whereas most is emulsified in a cream layer.

TL;DR: C. taiwanensis exhibited high promise for reducing the production cost of P(3HB- co -3HV), and incorporated a wide range of 3-HV into PHA from soluble starch and valerate as a mixed carbon source.

TL;DR: The first report on the production of lipases by B. ribis grown on these different carbon sources is reported, and the crude lipase showed affinity for substrates of short, average and long-chain fatty acids (different esters of p -nitrophenol and triacylglycerols).
